I bought all the necessary shyt to oxygenate my wort. My question is how "open" do I leave the regulator to oxygenate? Wide open? Quarter turn? I don't want to over or under oxygenate. Thanks in advance!

yup.. and from my understanding (not to cause debate), you can't over oxygenate wort. You'll just waste the oxygen is all. Anything that isn't used by yeast gets forced out by Co2.

I used to use a stone in the fermenter for about a minute or two kinda swirling it around. Now I have an inline oxygenation system that is connected to the wort out of my plate chiller. I turn it on for half the batch then turn it off. It works amazingly well. It's crazy too when the wort runs with oxygen it turns almost white in the tube.

I was just reading a study done regarding oxygenation of wort so this thread caught my eye. According to the guy who wrote this piece you can, in fact, get o2 levels to the point it becomes toxic to the yeast. Here's a link to that study:
